Eggs are one of the most complete foods nutritionally and one of the most efficient protein sources per dollar. They provide high-quality protein, healthy fats, and essential nutrients in a convenient serving. Their calorie and protein content can vary slightly depending on egg size, preparation method, and whether you eat the whole egg or only the white. Here’s everything you need to know about the numbers.
Quick Answer: How Many Calories and How Much Protein Are in an Egg?
One large egg contains approximately 72 calories and 6.3 grams of protein. Most of the calories come from the yolk, while the protein is divided between the egg white and yolk. Egg size and cooking method can slightly change the final calorie and protein amounts.
Egg Nutrition at a Glance
Per 1 large egg (50g):
| Nutrient | Whole Egg | Egg White Only | Egg Yolk Only |
| Calories | 72 | 17 | 55 |
| Protein | 6.3g | 3.6g | 2.7g |
| Total Fat | 5g | 0g | 4.5g |
| Carbohydrates | 0.4g | 0.2g | 0.6g |
| Cholesterol | 186mg | 0mg | 186mg |
How Many Calories Are in an Egg?
A single large egg has about 72 calories. The yolk carries 55 of those, which is why egg white-only preparations are lower in calories.
By cooking method:
| Preparation | Calories (per large egg) |
| Raw | 72 |
| Hard-boiled | 78 |
| Soft-boiled | 78 |
| Poached | 71 |
| Scrambled with no added fat | 91 |
| Fried in butter | 90 to 100 |
The differences between methods are small. How you cook an egg matters less than what you cook it in. A tablespoon of butter adds about 100 calories.
How Much Protein Is in One Egg?
One large egg has 6.3 grams of protein. The protein is split almost evenly between the white (3.6g) and the yolk (2.7g), so removing the yolk cuts your protein intake nearly in half.
Egg protein is considered one of the most bioavailable proteins available, meaning the body uses a very high percentage of it. Cooked egg protein has slightly higher bioavailability than raw.
By egg size:
- Small egg (38g): 4.9g protein, 54 calories
- Medium egg (44g): 5.5g protein, 63 calories
- Large egg (50g): 6.3g protein, 72 calories
- Extra-large egg (56g): 7g protein, 80 calories
- Jumbo egg (63g): 7.9g protein, 90 calories
How Many Eggs to Hit a Protein Target?
- 15g protein: About 2.5 large eggs
- 20g protein: About 3 large eggs
- 30g protein: About 5 large eggs
If you’re combining eggs with other protein sources at the same meal, 2 to 3 eggs is usually enough to make a meaningful contribution.
Eggs vs. Other Breakfast Proteins
| Food | Calories | Protein |
| 1 large egg | 72 | 6.3g |
| 2oz turkey sausage | 120 | 14g |
| 1/2 cup Greek yogurt | 75 | 13g |
| 1oz cheddar cheese | 113 | 7g |
| 2 strips bacon | 86 | 6g |
The Yolk Debate
The yolk contains all the fat and cholesterol in an egg, plus a majority of the micronutrients: vitamin D, B12, choline, lutein, and zeaxanthin. Removing the yolk to cut calories removes most of the nutritional density along with it.
For most healthy people, eating whole eggs in normal quantities is fine. The current consensus is that dietary cholesterol in eggs doesn’t significantly affect heart disease risk for most people, and the nutrient profile of the whole egg is substantially better than egg whites alone.
If you’re tracking macros and want to reduce calories, using a mix of whole eggs and egg whites (2 whole eggs plus 2 whites, for example) is a common approach that keeps the flavor and some of the yolk nutrients while reducing total fat and calories.
Final Thoughts
Eggs provide high-quality protein, healthy fats, and several essential vitamins and minerals in a relatively low-calorie serving. Whole eggs offer more nutritional value than egg whites alone, although combining whole eggs with additional whites can help reduce calories and fat. Your total calorie intake will also depend on the cooking method and any butter, oil, cheese, or other ingredients added.
